Casdoor, the Go package github.com/casdoor/casdoor, is vulnerable to server-side request forgery through its Webhook URL handler in versions up to and including 1.1000.0. A remote attacker can manipulate the webhook URL to make the server send requests to destinations of their choosing. No fix is listed, and the source gives few other details.
